A bimetallic complex CoII VIV
L2+ has been synthesized with binucleating macrocyclic ligand
prepared by condensing 2 equiv. of 2,6-diformyl-4-methylphenol with 2 equiv. of
1,2-phenylenediamine. This has been immobilized by covalently binding it on a
carbamate modified alumina support. The TGA analysis of the final catalyst
shows that it is thermally stable up to 251oC and it has been shown
that it serves as an oxidation catalyst for n-octane
oxidation. During the reaction, there is no change of molecular structure
(i.e., absence of cracking or isomerization) and the four oxidative products
are 2-octanone (1.5%), 3-octanone (1.2%), octanol (2.6%) and octanoic acid
(0.5%) at 150°C.
